Question

1000-х=35+6·8 81:у=63:7 Х·8=100-(4·9)

Answer 1

1000-х=35+6·8

1000-x=35+48

1000-x=83

x=1000-83

x=917

81:у=63:7

81:y=9

y=81:9

y=9

Х·8=100-(4·9)

8x = 100-36

8x=64

x=64:8

x=8

Answer 2

To solve the equations, let's go step by step:

1. 1000 - x = 35 + 6 * 8

Let's first solve the right side of the equation:

35 + 6 * 8 = 35 + 48 = 83

Now, the equation becomes:

1000 - x = 83

To find the value of x, let's isolate it on one side. To do that, we need to move the constant term to the other side of the equation:

x = 1000 - 83 x = 917

So, the value of x is 917.

2. 81 / y = 63 / 7

To solve for y, cross-multiply:

81 * 7 = 63 * y

567 = 63y

Now, isolate y:

y = 567 / 63 y = 9

So, the value of y is 9.

3. x * 8 = 100 - (4 * 9)

Let's first perform the operations inside the parentheses:

x * 8 = 100 - 36

Now, isolate x:

x = (100 - 36) / 8 x = 64 / 8 x = 8

So, the value of x is 8.

To summarize: x = 917 y = 9 x = 8
